Abstract
As the core infrastructure of cloud computing, a large scale of the data center networks (DCNs), which consist of millions of servers with high capacity, suffer from node failure such that the reliability is deteriorated. Malicious group could inevitably compromise the quality and reliability of data; thus, how to ensure the security routing of data is an urgent practical problem. As models for large-scale DCNs, it is worth mentioning the balanced hypercube, which is well-known for its strong connectivity, regularity, and a smaller diameter. Each of which makes a balanced hypercube a trustworthy model to deal with data traffic and provides a certain degree of fault-tolerance as well. In this paper, we use the balanced hypercube as a model for the data center networks and design a reliable safety level by referring to different safety levels of related subgraph. This subgraph contains the source and destination nodes, and the shortest feasible paths are located so that the reliable transmission is achieved. Then, we get that the length of fault-tolerant safety routing of data center networks based on balanced hypercube is always no greater than the Hamming distance plus two. Experiment shows that our fault-tolerant security routing scheme is more effective in the same reliable network environment of DCNs.
Highlights
With the advent of 5G mobile communication technology, demands for network information and user are increasing
data center networks (DCNs) fall into two main categories: switch-centric and server-centric
We study the (t, k)-diagnosability of balanced hypercube under the PMC model [31]. e data center network based on the balanced hypercube model is very suitable for increasingly complex network structure
Summary
With the advent of 5G mobile communication technology, demands for network information and user are increasing. Fault-tolerant routing means that efficient transmission of information routing can still be found when there is a certain number of fault nodes in the network systems It is an important application in different networks and has been studied extensively in the literature. E main motivation of this study is to propose an efficient fault-tolerant security routing of BHn-based data center network, and our ideas come from [6, 32]. Experiment shows that our fault-tolerant security routing scheme is more effective in the same reliable network environment of DCNs. We organize our paper as follows.
